Application filed June 15, 1925. Serial No. 37,301.

To all whom z'tmay concern:

Be it known that I, A oNzo B. PAnKnR, a citizen of the United States, residing at Sylacauga, in the county of- Talladega and State of Alabama,-have invented a'ne'w and useful Fire Hydrant, of which the following is a specification. V This invention relates to hydrants and more particularly to fire hydrants.

v The object ofthe invention is to construct a hydrant of this character so that 1t-rnay be repaired without digging up the street -or sidewalk and without taking the hydrant apart down in the ground.

Another object is to provide ahydrant of this character equipped with avalve casing and valve-seat which may be securely held in operative position and readily removed when desired for repairs or otherwise. 7

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the com bination and arrangement of parts and'in thedetails of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings Figure 1 represents a vertical section of a fire hydrant constructed in accordance with this invention and shown connected with a water main;

-Fig. 2 is a transverse section taken on the-line 22 of Fig. 1; and c Fig. 3 is a similar view taken on the line I 33 of Fig. 1.

I11 the embodiment illustrated an Lshaped casing 1 is shown, the short arm 2 of which is designed to be secured to aflwater main M in any suitable manner. The long or upright arm 3 is equipped with the usual plug openings 4 and is divided at its upper end with a laterally extending flange 5 between which and a flange 8 on a cap 7 is clamped a plate 9, packing 10 being preferably arranged between these members to insure a water tight connection, the cap 7 has an opening in the top in which a plug 11 is swiveled and which has its outer end 12 made angular to receive a wrench, its inner end being threaded externally to receive a nut 13. This inner plug end is made hollow and internally threaded to receive the threaded end of a valve stem 14 which passes through a gland 15 in the plate 9.

Thisvalve stem 14is made angular in cross section at its lower end as shown'at 16 and passes through a correspondingly shaped opening in a spider 18'of a valve seat 17. This angular formation ofthe end l6adapts the valve stem 14 to be reciprocated longitudinally without being turned within the valve cage. I

The valve seat 17 1S removably mounted on a seat 19 formed in the lower end of the casing arm 3 and is engaged by a beveled valve 21 carried by the stem 14 and secured in adjusted position on said stem by a lock nut 22.

The valve or seat 17 is provided with a drain conduit 23' normally closed by a spring pressed valve 24 a stem 25 of which projects into the path of valve 21 so that p when the valve 21 is seated to close the easing 3 valve 24 is opened to permit any water which may be in said casing to drain out through the conduit 23.

The valve seat 17 is provided with a plurality of seats 26 four being here shown and which are designed to receive the heads 28 of rods 27'four of which are shown which have threaded engagement at their upper ends with lugs 29, said lugs being removably mounted in the side walls of the casing 23 adjacent plate 9. As shown these lugs 29 have laterally extending threaded studs 30 which extend through openings in the side ative position. In the use of this hydrant the cap 7 having been removed together with plate 9 the valve seat 17 with the .walls of the casing 3 and the lugs in operclosed by turning the plugcl2. 'When valve 7 21 is drawn up tightly on to its seat as shown in 1 the valve stem 25 engages said valve 21 and opens the valve 24 against the tension of its spring and thus permits any water which may have collected in the casing 3 to drain out through the outlet 23.

\Vhen the hydrant?- is to he us=ed the hose is comm-ted with the outlets l; in the usual. uianne and the valve 21 opened to permit the water to flow through she easing 3 and pasa out; of the outlets =;l-.

From the ahoYe description it will be ohvious that the "valve ll and the seatl? may he i-eadil removed for repairs or otherwise without molesting the nut-rounding earth and h simpl removing the cap '7 and plate t) and alter repairs have heen made they;' may he quickly replaced ready For use.

A, hydrant, eonati'uvt'ed an shown herein and LltSLllllltl. does away with all. screws and lIlHlBWlS in the casing and seat- 1?.

A l'llO hydrant: comprising a substantially Lhhaped easing, one arm arrangez l verticall; and equipped at its upper end with a onto its seat to 'lHJOVldO a wa ter tight; joint.

In testimony that I olaim the foregoing as my own, 1 have hereto afl'ixed my signature.
